Postulation of genes for resistance to powdery mildew in spring barley cultivars registered in the Czech Republic from 1996 to 2010

Popis výsledku v původním jazyce

Powdery mildew caused by the airborne biotrophic fungus Blumeria graminis f. sp. hordei is a common disease of barley. Although it can be controlled by fungicide applications, genetic resistance is an efficient and more environmentally acceptable way oflimiting its effect on yield and quality. Spring barley is the second largest cereal crop in the Czech Republic and seventy spring barley cultivars (cvs.) were registered from 1996 to 2010. Seedlings of 43 cvs. were tested for reaction to selected isolates of the pathogen and resistance genes were identified using the postulation method. The following 12 known resistance genes were postulated namely, mlo, Mla6, Mla8, Mla12, Mla13, MlaRu4, MlaN81, Mlg, MlLa, Ml(Ab), Ml(Ro) and Ml(St) and two unknown resistances were found in Paulis and Prosa. Four cvs. (Azit, Paulis, Respekt and Tocada) were heterogeneous for mildew response. The most frequently found gene was mlo, which was present in 29 cvs. In nine of 15 cvs. without mlo, Mlg occurred
